Experimental Investigation of Thermal Balance of a Turbocharged SI engine Operating on Natural Gas

This paper experimentally investigates the thermal balance and performance of a turbocharged gas spark ignition engine. The First Law of Thermodynamics was used for control volume around the engine to compute the output power, transferred energy to the cooling ﬂuid, exhaust gases and also unaccoun...
